For some odd reason Image Backups (incremental and full) had stopped working. I have completely uninstalled/removed and reinstalled the client and server. Prior to connection via the internet/password authentication the Image settings tab was present within the client settings. After the client established connection with the server the tab has gone missing. I can’t find a setting on the server that would account for this. I can force an incremental or full image backup to start from the server but automatic backups are not occurring.
Is it possible you have “Do not do image backups” option checked in Settings -> General -> Server settings?
I suppose the server would then push the option to client and it would disappear in the client UI.
